The train network is essentially at a standstill after wild storms swept through Sydney.
Trains are not running between Parramatta and Richmond, or between Parramatta and St Marys on the T1 Western Line, T5 Cumberland Line and Blue Mountains Line, with severe weather causing power supply issues at various locations.
Limited trains are still running between the city and Parramatta, and between St Marys and Penrith and Blue Mountains Line stations.
Tens of thousands of commuters will be impacted as the evening peak arrives.
“Passengers are advised to delay their trip, consider alternative travel arrangements or allow plenty of extra travel time,” the Transport Management Centre said.
Replacement buses have been called in but delays are expected to last for hours.
It follows wild weather that came through Sydney earlier today and continues in parts of the city.
Meanwhile, L4 Westmead & Carlingford Line light rail services are still not running between Carlingford and Rosehill due to fallen overhead wires near Carlingford.
